The Columbia River serves as the dominant geographic and industrial spine for this riverfront landscape at the Washington and Oregon border. In the north, the industrial hubs of Longview and Kelso are marked by extensive infrastructure including the Log Pond, Port of Longview, and Kelso-Longview Airport. This reach of the river is characterized by complex waterways such as Slaughters Channel and Carrolls Channel, which wrap around massive islands like Lord Island and Cottonwood Island.
